" Ant ipathes ramosa, pinnata, hispida; piniiulis setaceis alternis, pinnulis aliis (sed 

 raris) transverse exeuntibus" (E. and S., op. cit., p. 101). 



The stem and primary branches are strong. The smaller branches are arranged 

 irregularly, and bear a number of simple, subequal, moderately distant pinnules, not over 

 4 to 5 cm. long, most of which are lateral and subalternate, but a few arise at irregular 

 intervals from the anterior or antero-lateral surface. The polyps are small, rather 

 crowded on the pinnules, but very distant on the main trunks. 



I am indebted to Dr. Dohrn, of the Naples Zoological Station, for a portion of a 

 specimen of this species in which the polyps are beautifully preserved. This specimen 

 undoubtedly agrees with Lacaze Duthiers' description and figures of the spines, &c, and 

 is probably the same form as that described by Ellis and Solander, though it differs in 

 one or two points from their description and figures. 



My specimen consists of the upper portion of a stem, 24 cm. long and 1*5 mm. in dia- 

 meter at the base. The stem bears branches and branchlets laterally on both sides, but 

 those on the right are more numerous and important. The main branches (in this, the 

 upper part of the corallum) are 8 to 1 cm. long and from 2 to 4 cm. apart, with a few simple 

 or branched pinnules between them. The larger branches are bipinnate, but the arrange- 

 ment and size of the pinnules is most irregular. One of the larger branches has three 

 branchlets, which are given off from the lower portion of the branch, at points not situated 

 on the lateral margin, and not all in the same plane. These are 4 to 5*5 cm. long, and 

 bear a number of simple pinnules 1 to 2 cm. long. These are arranged quite irregularly, 

 and there may be four or five on one side and only one on the other. In the upper and more 

 tapering portion of the branch, a number of simple pinnules from 1 to 2 cm. long are 

 arranged subalternately, about nine to 4 cm.; these are more nearly lateral in origin. In 

 other portions a few of the pinnules and pinnate branchlets are arranged in a plane almost 

 at right angles to that of the majority. 



In the upper portion of the specimen the stem bears pinnules from 2 to 6 cm. long, 

 arranged quite irregularly, one here and there passing out in a plane almost at right angles 

 to the others. The larger ones, which may be considered branchlets, are laxly and 

 irregularly pinnate. The pinnules are here about 0'5 cm. apart and vary very much in 

 length; most are lateral, but, occasionally, one is directed obliquely in another plane. 

 The shorter pinnules are all simple, as indeed are many of those of medium length, whilst
